HEAD-CHAI R FOR RAILWAY -SWITCHES.

.EPECIEI'CATIQN forming part of Letters Patent No. 351,234, dated October 19, 1886.

Serial No. 195,443. (No model.)

To all whom it may concern:

Be it known that I, FREDRIC O. \VEIR, of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Head-Ohairs for Railway-Switches, of which the following is a specifieation.

My invention relates to an improved headchair for railway-switches.

The object of my invention is to provide a cheap, firm, and durable device, all of which will be set forth in the description of the ac companying drawings, making a part of this specification, in which Figure 1 is a perspective view of my improvement. Fig. 2 is a bottom perspective view of the cutter lip or lug. Fig. 3 Ba detail view of the spacing-bar. Fig. 4 is a perspective view of one of the side lugs.

A represents the bed-plate of the chair.

B represents the side lugs between which the switch-rail moves. These lugs are rigidly secured to the bed-plate by rivets or other suitable means.

0 represents the pacing-ban Its ends are provided with gains 0, and are held down by the overlapping of the side lugs, B.

D represents the cutter lip 01- lug. The forward end is provided with a shoulder, 1, and an overhanging flange, 2. The shoulder 1 rests firmly against the spacing-bar O, and the flange 2 projects over the top to assistin hold- The outer edges, 4

and 5, of the cutter-lug D are gained or rounded off, so as to fit the upper and inner surfaces of the flange of the two rails, which abut under the lip or lug D.

E F represent side lips, which are securely riveted to the base-plate A. The inner edges of both of these lips are respectively upturned and shaped to fit the recess upon the outer surface of the flange of the rails.

a I) represent the space occupied by the two rails upon either side of the central lug, D.

The lips of the lugs D E F rest uponand firmly hold the main rails in position, and the switch-rail is held in either of its extreme positions alternately by the lugs B B, and the moving switch-rail and fixed rails are held against longitudinal movement by the spacingbar 0, against which they respectively abut. By this means a head-chair is produced that is more elastic as a j oi nt-chair for the switches, and in consequence the life of the switch-rails is prolonged, and at the same time a firm and sufficiently rigid joint is obtained.

I claim 1. A head-chair composed substantially of the base-plate A, to which is securely fastened the parts B O D E F, substantially as specified.

2. In ahead-chair, the spacing-bar O, secured thereto by one or more of the middle lips, D, and the side lugs, B B, substantially as specified.

3. In ahead-chair, the spacing-bar O,secured thereto by one or more of the middle lips, D, and the side lugs, B B, each provided with abutting shoulders and overhanging flanges, substantially as specified.

In testimony whereof I have hereunto set my hand.

FREDRIO O. WEIR.
